Heatable pressurizing device for blood transfusion in hematology department

Abstract

The invention relates to the field of medical auxiliary instruments. The heatable pressurizing device for blood transfusion in the hematology department comprises a shell, and the shell is composed of an extrusion area and a heating temporary storage area arranged at one end of the extrusion area; a blood bag groove used for containing a blood bag is formed in the middle of the extrusion area and extends in the length direction of the extrusion area. Two sets of step-by-step extrusion mechanisms are symmetrically arranged in the shell on the two sides in the blood bag groove, and extrusion openings extending in the length direction of the blood bag groove are formed in the groove walls on the two sides of the blood bag groove; the step-by-step extrusion mechanism comprises a row of extrusion frames which are sequentially arranged in the length direction of the blood bag groove. The blood bag can be extruded step by step from one end to the other end, then blood in the blood bag is completely extruded out, waste of the blood is avoided, and the utilization rate of the blood is increased.

Description

technical field [0001] The invention relates to the field of medical aids, in particular to a heatable and pressurized device for blood transfusion in the department of hematology. Background technique [0002] Blood transfusion refers to the treatment of supplementing the blood volume of the patient by injecting blood into the patient's body from a vein. It is widely used in the emergency treatment of massive hemorrhage. In order to improve the blood transfusion rate, in some critical cases, the method of manually squeezing the blood bag can be used to increase the blood transfusion pressure, thereby improving the blood transfusion efficiency. However, in the actual clinical process, this traditional method requires medical staff to continuously press the blood bag, which increases the labor intensity of medical staff; In the third aspect, this method cannot completely squeeze out the blood stored in the blood bag, resulting in more blood remaining in the blood bag, result...

AI Technical Summary

Problems solved by technology

However, in the actual clinical process, this traditional method requires the medical staff to continuously press the blood bag, which increases the labor intensity of the medical staff; secondly, due to manual operation, the pressing pressure cannot be accurately grasped. In the third aspect, this method cannot completely squeeze out the blood stored in the blood bag, resulting in more blood residue in the blood bag, resulting in greater waste; at present, although the existing technology Partially automated blood transfusion pressurization equipment has appeared, but it mainly focuses on the improvement of the first aspect, that is, by replacing manual work with automation, the mechanized extrusion of blood bags is realized, which alleviates the labor of medical staff to a certain extent. Intensity, but in the other two aspects, the existing pressurized blood transfusion device still has a big deficiency
